NIST The "setNamedItemNS(arg)" method for a NamedNodeMap should raise INUSE_ATTRIBUTE_ERR DOMException if arg is an Attr that is already an attribute of another Element object. Retrieve an attr node from the third "address" element whose local name is "domestic" and namespaceURI is "http://www.netzero.com". Invoke method setNamedItemNS(arg) on the map of the first "address" element with arg being the attr node from above. Method should raise INUSE_ATTRIBUTE_ERR DOMException. Mary Brady 2001-08-17
